Trustmark (TRMK) Stock Looks Cheap On Its 131% Three Year Run

Simply Wall St·09/11/2026 00:37:29
Listen to the news

Trustmark has put up a powerful run over the past three years, yet the current share price still sits well below an intrinsic value estimate from the Excess Returns model, while market multiples look much closer to fair.

  • The stock has delivered a 130.5% return over three years. This puts extra pressure on today's buyers to judge whether that past strength already reflects the bank's earning power.
  • Future valuation can benefit if Trustmark converts its balance sheet into steadier excess returns on equity. However, loan quality or funding costs that move the wrong way may limit how much value investors are willing to ascribe.
  • On a broader set of checks Trustmark screens as a mixed picture rather than a clear bargain or clear overvaluation, with a value score of 4.0 that lines up with roughly "about right" trading multiples.

The issue now is whether that intrinsic value estimate still leaves a meaningful margin between Trustmark's current price and what its underlying economics justify.

Does Trustmark Look Undervalued on Excess Returns?

The Excess Returns model estimates what Trustmark can earn on its equity above its own cost of capital, then capitalises that surplus into an intrinsic share value. For Trustmark, the framework uses a book value of $36.82 per share and a stable EPS estimate of $4.44 per share, based on analyst views for future return on equity.

The model assumes an average return on equity of 11.16% against an equity cost of $2.88 per share. This implies excess return of $1.56 per share and a stable book value rising to $39.76 per share. Using those inputs, the Excess Returns approach produces an intrinsic value of about $83.87 per share, which is higher than where the stock trades today and implies a 43.4% discount.

On this Excess Returns view, Trustmark currently appears undervalued relative to its estimated intrinsic worth.

Where Does Trustmark Sit on Earnings?

P/E tends to be a useful yardstick for a bank like Trustmark because earnings power is central to how investors weigh its long term appeal.

Trustmark trades on a P/E of about 11.8x, which is very close to the broader Banks industry on roughly 11.8x and peers around 12.1x. That places the stock in the middle of the pack rather than at a clear premium or discount based purely on earnings.

The Fair Ratio for Trustmark is calculated at about 10.8x, based on its specific mix of profitability, risk and size. The current 11.8x is only slightly above that mark, so the market price lines up reasonably with what this tailored benchmark suggests investors might pay for the bank's earnings stream.

On the P/E lens, Trustmark shares look priced roughly in line with what its earnings profile would justify.

The Bottom Line

Trustmark screens as undervalued on the Excess Returns intrinsic value estimate, while its P/E sits close to what peers trade on. That mix points to a stock where the gap between price and intrinsic value only closes if the bank keeps turning its equity base into consistent excess returns. The crux for both bulls and bears is whether loan quality and funding costs stay disciplined enough for that earnings profile to hold.
